+The intended primary use case is for content creators who need to split large video files into smaller 
+segments for platforms like TikTok, Instagram Reels, YouTube Shorts, or similar. The smart 
+cropping feature allows the tool to automatically detect and keep faces or bodies in the frame 
+when splitting, ensuring that important content is not cut off.

+Splitter uses cutting-edge body-detection CV models to analyze the video and determine optimal 
+cropping regions for each segment. Smooth tracking and gravitation bias ensure that the cropping remains
+stable and focused on the subject without excessive jitter or erratic movements. 
+The tool can also correct for rotation metadata to ensure proper orientation in the output segments.

+Splitter uses FFmpeg for the actual splitting and encoding, with multi-threading to maximize performance.
